Narva's 100/55W ultra high high beam H4 bulb, is a huge high beam improvement over the stock 60/55W bulbs most bikes come with.
If you are looking to get more lighting out of your stock headlamps these are the bulbs you want!
Below is a list of some of the bikes this bulb should be compatible with.
If your bike isn't listed just check your owners manual to see if it takes an H4 bulb.
